| Opening the top of a Hafler p-1500 amp. Please If it was put together it should be capable of being taken apart.Find a 13 year old! just kidding......That would be if you had a computer problem.Some kind of spring clip? I'll look the amp up and checkout whatever photos are available. | |
| Fun Little Project for improving Dynamics IF the baggies are tucked out of site, try a test.When you are gone, have someone remove....or NOT remove, the baggies in question.Then record your answer to 'baggie, yes/no'. Do 20 trials over a period of weeks and see if you score significantly ... | |
| Opening the top of a Hafler p-1500 amp. Please UNPLUG IT IMMEDIATELYLet it sit for a couple hours....caps can hold a charge, even in preamps.Try the 'shake it out' routine per instructions above.Even something as tiny as a screw can bridge a couple traces on a board or otherwise SHORT somethin... | |
| Can you overpower a speaker A speakers ability to absorb power decreases as it gets hot....and the Electrical characteristics change. Mostly for the worse.In short (no pun intended) too much power is for sure possible. Even perhaps, when no audible distortion is present, you... | |
| Filling a 6600 Cu. ft. room A space that large would benefit from multiple subs....even if you have to buy 'less' sub but more of 'em. Example:: Spend 3 large on a single mondo sub. OR half that each on a pair? I think the pair would yield more uniform bass and just as good ... | |
| Survey-What is your most used source? #1 Small Dish receiver. XM and Sirius feeds. This when I do housework, work in the yard or over Christmas for the holiday feeds.Same receiver feeds TV audio thru the same system.#2 CD player. This also acts as a DAC from the DVD and Small Dish rec... | |
| turning my system on during lightning storms I was in Palm Springs CA. a few summers ago doing some house sitting. A rare summer storm blew thru. At least 3 or 4 lightning strikes within a couple blocks. It rained like no tomorrow for about 2 hours.....than on to hot and humidThe damage? The... | |
| speaker level sub hookup on class D? Kij,Yes, and I'd expect the 250ASP to also have 2 voltages. Since I own the ASP500 I haven't bothered to look at the other 2 modules. Don't forget...and I don't know how this plays into it, that these modules are designed to power other B&O mo... | |
| speaker level sub hookup on class D? Thanks for half/full notes:I think the IR module I have out in the garage is ALSO half bridge. The IR white paper lists some considerations for the designer when choosing to go with full or half bridge.Isn't the 500ASP also 80v? My spec sheet list... | |
| Any one ever replace caps or modify there Xovers NOTE: I didn't actually say to go ahead and DO the mod. Parts ain't parts. Caps have a resistive and inductive component.Inductors? Resistive and perhaps capacitive as well. Point being? Changing parts is perhaps a little MORE complex than just ma... | |
| speaker level sub hookup on class D? Good to know.....ICE is 'half bridge' topology and makes sense for the whole thing to 'float'. | |
| Any one ever replace caps or modify there Xovers UH? Can't you just LOOK at it and draw the Sketch-o-matic? The DCR for the inductor can be measured.....amp off and lift one leg. The problem would be the inductor value. That, too, can be measured.Start tracing wires.....and maybe take a few photos. | |
| Magnepan 1.6 vs. B&W 805N You mention 'the room'.....always a sticking point with panels. IF your room is not panel friendly you'll end up with some dynamic solution.IF you can stick with panels and like the W4S solution, you can shop across the B&W ICE line. Many manu... | |
| Anyone tried changing OPAMPS in Music Hall A25.2? Can't recommend you install a socket unless you have both the skillset and the right stuff. Solder sucker? Solder wick? Real low power iron? Adjustable? Good, hi-end socket? 'Modified' opamp? How so? Unless manufactured from a new set of masks and... | |
| Anyone tried changing OPAMPS in Music Hall A25.2? I made a headphone amp using OPA 2132s. Similar but more stable version of the OPA 2134, apparently. this is the stereo version of your OPA 134, I think.Are your opamps socketed? Easy to do 'opamp' rolling at that point, since they all have same p... |
